FORM OF SPOOL FOR TEXTILE YARNS Filed June 17, 1935 Mmi By His 14/701g:- a /Z Patented May 4, 1937 FORM OF SPOOL FOR TEXTILE YARNS JohnBrandwood, Birkdale, Southport, England Application June 17, 1935,Serial No. 26,971 In Great Britain June 28, 1934 1 Claim.

The present invention relates to spools upon which textile yarns andthreads are wound, and more specifically, to that form of spool in whichthe body or barrel is formed of wires or rods placed equidistantlyaround the longitudinal axis of the spool and parallel to such axis.Generally such spools have been provided with flanges into which theends of the wires or rods fitted.

I find that where a spool of textile threads is to be treated with dyesfor the colouring of same, the dye being applied to the exterior of thewound spool and then drawn radially through the thread masssee thespecification of British Letters Patent No. 294,504 granted to me-it isdesirable that at any point where colour is applied to be drawn throughas mentioned, a wire or rod of the spool should not occur, as the workis thus rendered uneven due to the obstruction.

It is the object of the present invention to provide a form of spoolwhich will ensure that no wire or rod forming part of the yarn-bearingsurface of the spool shall be permitted to interfere with the freepassage of colouring matter radially through the spool, and to this endthe invention comprises a flangeless spool having a barrel or bodyconsisting of wires parallel with and placed equidistantly around thelongitudinal axis of the same, connecting and spacing end portions ofarcuate form, rigid, and be- 3() ing in staggered relation, and thewhole being formed from a continuous length of wire.

Such a spool as to the individual wires of the barrel or body is strongand as to any adjacent pair of individual wires of the barrel or body 35connected by an end portion is slightly but sufficiently resilient topresent no obstacle to angular movement being imparted to the spool whennecessary, to adjust any wire to any desired position relative to thethread mass wound upon 40 it and being treated.

The construction of a form of the spool according to the invention willnow be described for a full understanding of the invention, referencebeing had to the annexed drawing. In the draw- 45 ing Figure 1 is a Viewin isometric projection of a complete spool; and Figure 2 is an end viewof the same.

A cylindrical mandrel may conveniently be employed, having upon itssurface recesses for 50 the reception at the necessary points ofremovable metal pegs, and around which pegs the wire may be bent to therequired shape. A continuous length of wire, for example of stainlesssteel, is taken and is bent around these pegs;

55 Referring to the drawing, Figure 1, the bending, with eight parallellengths of wire as shown forming the barrel body of the spool, iscarried out as follows:

An end of the wire being at point a: the said wire is brought to the1eftthis length being indicated as |and it is then bent to form thearcuate end 2; thence a straight length Ia and a bent portion 2a;straight portion lb and bent portion 3; straight portion lo and bentportion 3a; straight portion Id and bent portion 5; straight portion isand bent portion 4a; straight portion l f and bent portion 5; thenstraight portion lg and bent portion 5a. The extremities of the wire Iand. 5a having now met at the point x, the spool, bent as described, isremoved from the mandrel, the removal of pegs permitting this, and theends of straight length of wire I and bent portion 5a are securelywelded as by butt welding in the manner known to metal workers. Thespool now presents in end view a series of parallel wires forming theyarn bearing barrel or body, and the joining ends 2, 3, 4 and 5 on theend of the spool are in staggered relation to the joining ends 2a, 3a,4a, and 511, on the other. See also Figure 2.

The end portions or joinings in the above description are arcuate inform, and this is useful inasmuch as the yarns or threads when woundupon the barrel or body wires i, la present a plane surface between anytwo such wires. The projection of an arcuate end portion thus serves asa limiting and controlling point for the yarn or thread coilslongitudinally of the spool. The barrel or body wires may be closertogether than as described and illustrated, thus increasing the munberof wires for any given diameter of spool with a corresponding increaseof the number of arcuate end portions.

For a spool of for example eight inches in length a round section wireof a diameter of three-eights of an inch is found sufficiently strong.The wire may however be of any other section which can be suitablyworked for the purpose of the invention.

I claim:-

A flangeless spool for textile yarns or threads, such spool having abarrel consisting of stiff wires parallel with and placed equidistantlyaround the longitudinal axis of the same, and connecting and spacing endportions which are in staggered relation and constitute arcs of twocircles the centres of which are coincident with the longitudinal axisof the spool, the whole material employed being a continuous length ofwire.
